a F'Tnz'aQ-pQiM support beingprefer My utian spewing 155 also moves downward turning about the stationary fulcrum 31. At a predetermined low point the end of lever will strike the bolt thus opening valve 2% and admitting compressed fluid to the cylinder 14. This will increase the pressure in the cylinder and cause it to rise and move the lever 30 away from valve 24.- so as to permit the valve to close. On the other hand, if for any reason the pressure becomes too great, causing the cylinder to rise too high, then in a similar manner the valve 25 will be opened to relieve the excess pressure. By this arrangement just the desired pressure can be always n'lainta-ined within the cushioning device. By utilizing cushioning devices having large clearances so that substantial cushioning movements may be had, the same will act like springs having very great deflections. An arrangement as described has; however, substantial advantages over a spring arrangement, both in the matter of uniformity of action and in the prevention of vibrations belng transmitted to the vehicle body.

In accordance with the provisions of the patent statutes, 1 have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodimentthereoi; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means What I claim as new and desire to secure by Letters Patent of the United States is:

ll. In an apparatus of the character de- 0 ibed, the combination of an engine, fluid cushions for supporting it, and means controlled by the movements of the cushions for neeaeae automaticallyregulating the pressure in said fluid cushions, said means admitting fluid upon. a predetermined movement in one direction and venting fluid upon a predetermined movement in the opposite direction whereby said engine is positioned within certain limits.

2. In combination, a support, an engine, and fluid cushion means carried by the support for sustaining the weight of the engine, said fluid cushion means comprising a cyli-nder and piston which are movable relatively to each other, and valve means actu ated by the movements thereof for regulating the pressure withinthe cylinder, said valve means admitting fluid upon a predetermined n'iovement in one direction and venting fluid upon a predetermined move ment in the opposite direction whereby said engine is positioned within certain limits.

3. The combination of a vehicle, an engine, and means for supporting the engine on the vehicle so as to prevent vibrations of the engine being transmitted to the vehicle body, said means comprising a cylinder and piston movable relatively to each other, a pipe for supplying fluid 'under pressure to the cylinder, a pipe for venting fluid from the cylinder, valves in said pipes, said valves being normally closed, and means controlled by the relative movements of the cylinder and piston which opens the valve in the supply pipe when the engine moves down a predetermined amount and opens the valve in the vent pipe when the engine moves up a predetermined amount.

in witness whereof, I have hereunto set my hand this 8th day of September, 1917.

WILLIAM EVERETT m PLANCK.
